This option is an advanced feature that allows direct manipulation of the running browser using Python code. You can also customize variables in the entire execution environment and perform operations such as modifying and assigning values. Here are some examples:
1. Use `self.browser` to refer to the current browser being operated. You can directly use Selenium's API to perform operations, such as `self.browser.find_element(By.CSS_SELECTOR, "body").send_keys(Keys.END)` to scroll to the bottom.
2. Define a global variable: `self.myVar = 1`
3. Manipulate the above-defined global variable: `self.myVar = self.myVar + 1`
4. Print the above-defined global variable: `print(self.myVar)`
5. Assign the value of a custom variable to the value extracted from a field: `self.myVar = self.outputParameters["Field Name"]`

If you want to record your custom variable as a field, please select the next option, "Get value of a Python expression (the "eval" operation)"

6. If you want to import and use a third-party library that the program itself does not carry, you need to first use tools such as pip to install this library locally, and then add the path of the installed library before import, like:
(1) In the system command line execute the following command to install the library:
pip install emotlib
(2) Write the following code in the code box:
sys.path.append("D:/Python38/Lib/site-packages") # Assume emotlib library exists in this path
import emotlib # Now you can use emotlib library
print(emotlib.emoji()) # Use one of its functions.
</pre>

To execute a large amount of code, you can simply write "outside:myCode.py" and the program will read and execute the code within myCode.py under the EasySpider directory.
This option is an advanced feature that allows directly returning the expression value of Python code, and in other places, use Field["FieldName"] to represent the return value of this operation.. Here are some examples:
1. Return relevant values of the current browser object. Use `self.browser` to refer to the current browser being operated. You can directly use Selenium's API to perform operations, such as `self.browser.find_element(By.CSS_SELECTOR, "body").text` to return the text on the current page.
2. Return the value of a custom global variable: `self.myVar`
3. Return the result of a conditional statement: `self.myVar == 1`
4. Determining whether the value extracted from a certain field is equal to the value of a certain variable: self.outputParameters["field name"] == self.myVar

Please note that this feature does not support assigning values to variables. In other words, you cannot write something like `self.myVar = 1`. If you want to perform assignment operations, please select the previous option, "Run Python code on current environment (the "exec" operation)"</pre>

Loop based on the expression value of Python code. Here are some examples:
1. Return relevant values of the current browser object. Use `self.browser` to refer to the current browser being operated. You can directly use Selenium's API to perform operations, such as `self.browser.find_element(By.CSS_SELECTOR, "body").text=="123"`, which checks whether the current page contains the text "123".
2. Return the value of a custom global variable: `self.myVar`
3. Return the result of a conditional statement: `self.myVar > 1`
4. Determining whether the value extracted from a certain field is equal to the value of a certain variable: self.outputParameters["field name"] == self.myVar
If the expression returns a value greater than 0 or evaluates to True, the loop continues; otherwise, it stops.
